[0004] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0005] When using the flip desk, the table top can be flipped over by pulling it in front of the body. However, in actual use, a large number of books are easily placed on the table, and the books are easily dropped from the table when the table top is flipped over, which is not suitable for students with a lot of schoolwork. Summary of the invention

[0006] In order to overcome the shortcomings of existing flip desks in actual application, that is, due to a large number of books placed on the desktop, the books are easy to fall off the desktop when the desktop is flipped up, which is not conducive to use by students with a lot of schoolwork, the embodiment of the present application provides a flip desk. When the limit bar on the control table board B is disengaged from the removal slot at the top of the limit slot, with the help of the cooperation of the supporting shaft rod and the T-slot, when the table board B moves relative to the table board A, a large space is left between the table board B and the table board A, and the books on the top of the table board B can be pushed to the inner side of the enclosure and received by the support plate, so that the books on the top of the table board B will not fall off, which is conducive to the folding of the table board B after flipping, and it is more convenient to use.

[0007] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0008] A flip-type desk comprises a desk board A, a desk board B and a bracket, wherein the desk board A is arranged in a U shape;

[0009] The bracket is assembled and fixed to the bottom of the table board A;

[0010] The table board B is T-shaped, and one end of the table board B is movably connected to the inner side of the table board A. Two limit grooves and two removal grooves are processed on the inner wall of one side of the table board A. The middle parts of both sides of the table board B are integrally formed with limit strips; the two limit strips are respectively located at the tops of the two limit grooves and are connected to the inside of the limit grooves. The two limit grooves are symmetrically arranged on both sides of the table board B, and the limit strip slides inside the limit groove, and the limit strip withdraws from the inside of the removal groove, supporting one end of the table board B to be inserted into the gap between the outside of the bracket and the inside of the table board A.

[0011] In a possible implementation, both side surfaces of one end of the table board B are integrally formed with support shafts, and the inner walls of the two corners of the table board A are processed with T-shaped grooves. The two T-shaped grooves are symmetrically arranged on both sides of the table board B, and the two support shafts are movably connected to the inside of the two T-shaped grooves.

[0012] In one possible implementation, the T-slot is T-shaped, and the table top B drives the limit bar to move from one end of the limit slot to the other end, and when withdrawing from the inside of the removal slot, the supporting shaft first slides from one end of the T-slot to the other end, and then rotates inside the T-slot.

[0013] In a possible implementation, the removal slot is located in the middle of the limit slot. When the table top B moves along the horizontal plane inside the table top A, it can drive the limit bar inside one end of the limit slot to move toward the direction of the limit bar and be plugged into the inside of the other end of the limit slot.

[0014] In one possible implementation, the inner side of one end of the table top A is threadedly connected with an axial bolt, and the outer sides of the two axial bolts are hinged with the same baffle; one side of the baffle sags due to gravity, so that the other side rests against the bottom of the table top B.

[0015] In a possible implementation, the bottom of the bracket is assembled with a panel, the middle inner walls on both sides of the bracket are assembled with adjustable columns, and one end of the adjustable column is assembled with a table leg; the two ends of the panel are respectively assembled and fixed to the tops of the two adjustable columns, and one side of the bottom of the two table legs is assembled with the same supporting leg frame.

[0016] In a possible implementation, the middle parts of the two adjustable columns are assembled and connected with a horizontal bar, the tops of the two horizontal bars are jointly assembled with a supporting plate, and one side of the supporting plate is adapted to be connected to the inner wall of the enclosure.

[0017] In a possible implementation, when the baffle is rotated around the axial bolt to one side, the bottom of the baffle is located at half of the shortest distance between the support plate and the table top A.

[0018] In a possible implementation, one side of the bottom of the table leg, the side of the support plate away from the enclosure, and the end surface of the bracket away from the enclosure are located in the same vertical plane, and when the baffle is in a vertical state, one side surface of it is flush with the vertical plane.

[0019] The beneficial effects of this application are:

[0020] First, in this solution, when the limit strip on the control table board B is disengaged from the inside of the removal notch at the top of the limit slot, with the help of the cooperation between the support shaft and the T-slot, when the table board B moves relative to the table board A, a large space is left between the table board B and the table board A, and the book on the top of the table board B can be pushed to the inside of the enclosure and received by the support plate, so that the book on the top of the table board B will not fall off, which is conducive to the table board B being turned over and put away, and it is more convenient to use;

[0021] Secondly, in this solution, a baffle is set between the inner walls at the opening of the bracket by using an axial bolt. During normal use, one side of the baffle can be drooped and the other side can be pressed against the bottom of table board B to limit the movement of the limit bar on table board B within the limit groove. When table board B moves relative to table board A and the book on the top of table board B is released to the inner side of the enclosure and received by the support plate, the baffle can be used to prevent the book from falling, which is more convenient to use.

[0028] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0029] Embodiment 1:

[0030] This embodiment introduces a specific structure of a flip-type desk. Figure 1-Figure 5 As shown, it includes a U-shaped table top A2, a T-shaped table top B4 and a bracket 12 assembled and fixed to the bottom of the table top A2, one end of the table top B4 is movably connected to the inner side of the table top A2, two limiting grooves 14 and two removal notches 3 are processed on the inner wall of one side of the table top A2, and the middle part of both sides of the table top B4 is integrally formed with limiting strips 13;

[0031] like Figure 1 and Figure 2 As shown, the bottom of the bracket 12 is assembled and connected with a panel 10, and the middle inner walls of both sides of the bracket 12 are assembled and connected with adjustable columns 9, and one end of the adjustable column 9 is assembled and connected with a table leg 7; the two ends of the panel 10 are respectively assembled and fixed with the tops of the two adjustable columns 9, and one side of the bottom of the two table legs 7 is assembled and connected with the same support leg frame 8, and the middle parts of the two adjustable columns 9 are assembled and connected with a horizontal bar 11, and the tops of the two horizontal bars 11 are jointly assembled with a support plate 6;

[0032] Among them, one side of the support plate 6 is adapted to be connected to the inner wall of the enclosure 10, and the support plate 6 and the horizontal bar 11 can be assembled and fixed to make the support plate 6 cooperate with the enclosure 10, and the support plate 6 is fixed to the inner side of the enclosure 10, so that a certain amount of books can be placed on the top of the support plate 6;

[0033] like Figures 3 to 5 As shown, both sides of the surface of one end of the table top B4 are integrally formed with a support shaft 16, and the inner walls of the two corners of the table top A2 are processed with T-shaped grooves 15;

[0034] Among them, by making two T-slots 15 symmetrically arranged on both sides of the table board B4, two supporting shafts 16 are movably connected to the inside of the two T-slots 15, and two limiting strips 13 are respectively located at the top of the two limiting slots 14 and are connected to the inside of the limiting slots 14. The two limiting slots 14 are symmetrically arranged on both sides of the table board B4. Because the T-slots 15 are T-shaped, when the table board B4 drives the limiting strips 13 to move from one end of the limiting slot 14 to the other end and withdraws from the inside of the removal slot 3, the supporting shaft 16 slides from one end of the T-slot 15 to the other end first, and then rotates inside the T-slot 15, which can support one end of the table board B4 to be inserted into the gap between the outer side of the bracket 12 and the inner side of the table board A2, so as to realize the folding work of the table board B4;

[0035] At the same time, when the table board B4 is controlled to rotate around the support shaft 16 inside the T-slot 15, the space inside the table board A2 can be opened, so that the book placed on the top of the table board B4 can be pushed to the inside of the surrounding board 10 and received by the supporting plate 6, which is simple and quick (and the distance that the table board B4 moves inside the table board A2 can be controlled by the length of the T-slot 15. When the support shaft 16 slides from one end to the other end inside the T-slot 15, a space can be left between the table board B4 and the table board A2);

[0036] Secondly, by locating the removal slot 3 in the middle of the limit slot 14, when the table top B4 moves along the horizontal plane inside the table top A2, it can drive the limit strip 13 inside one end of the limit slot 14 to move in the direction of the limit strip 13, and be plugged into the inside of the other end of the limit slot 14, thereby preventing the table top B4 from being in a horizontal state (that is, when the limit strip 13 is not cut out from the removal slot 3). Compared with the table top A2, the table top B4 can move a larger distance, which brings safety risks to the user.

[0037] The above design enables the limiting strip 13 on the table board B4 to move inside the limiting groove 14 on the inner wall of the table board A2, so that the inside of the removal slot 3 can be cut out to the top, and the supporting shaft 16 on the table board B4 first slides and then rotates in the T-slot 15 inside the table board A2, and finally supports the table board B4 to flip, so that one side of it is inserted into the gap between the outer side of the bracket 12 and the inner side of the table board A2, so as to facilitate the folding of the table board B4;

[0038] At the same time, when the limiting strip 13 on the control table board B4 is disengaged from the removal slot 3 at the top of the limiting slot 14, with the help of the cooperation of the supporting shaft 16 and the T-slot 15 (the length of the T-slot 15 needs to ensure that the distance that the table board B4 can move relative to the table board A2 is large enough), when the table board B4 moves relative to the table board A2, a larger space is left between the table board B4 and the table board A2, and the book supporting the top of the table board B4 can be pushed to the inner side of the enclosure 10 and received by the support plate 6. The book on the top of the table board B4 will not fall off, which is conducive to the work of folding up the table board B4 after it is flipped over.

[0039] Embodiment 2:

[0040] Based on Example 1, this example introduces the specific structure of the table top A2. Figure 1 and Figure 2 As shown, the inner side of one end of the table top A2 is threadedly connected with an axial bolt 5, and the outer sides of the two axial bolts 5 are hinged with the same baffle 1;

[0041] Among them, by making one side of the baffle 1 droop due to gravity, so that the other side thereof abuts against the bottom of the table board B4, when the limiting strip 13 is located inside the limiting groove 14, the table board B4 and the table board A2 are spliced ​​into a whole table board, and the friction between the baffle 1 and the table board B4 can be used to increase the resistance of the table board B4 relative to the table board A2 to ensure the stability of the application;

[0042] Secondly, when the baffle 1 is rotated around the axial bolt 5 to one side, the bottom of the baffle 1 is located at half of the shortest distance between the support plate 6 and the table A2. When the book is placed on the top of the support plate 6 through the opening side of the enclosure 10, it will not be blocked by the baffle 1. When there are a large number of books, the baffle 1 can be pushed to rotate around the axial bolt 5, which can release more space inside the enclosure 10.

[0043] Furthermore, by making one side of the bottom of the table leg 7, the side of the pallet 6 away from the enclosure 10, and the end surface of the bracket 12 away from the enclosure 10 in the same vertical plane, and when the baffle 1 is in a vertical state, one side surface of it is flush with the vertical plane. When the table board B4 is flipped up around the supporting shaft 16 and inserted into the space inside the table board A2 and outside the bracket 12, the user can lean against the side of the opening of the enclosure 10 to prevent books from falling from the top of the pallet 6.

[0044] The above-mentioned design sets a baffle 1 between the inner walls at the opening of the bracket 12 by using an axial bolt 5. During normal use, one side of the baffle 1 can be drooped and the other side can be pressed against the bottom of the table board B4 to limit the movement of the limit strip 13 on the table board B4 inside the limit groove 14. When the table board B4 moves relative to the table board A2 and the books on the top of the table board B4 are released to the inner side of the enclosure 10 and received by the support plate 6, the baffle 1 can be used to prevent the books from falling, which is more convenient to use.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
